Boys still have a hard dick when they sleep

Normal men will have morning erections, which is normal and not something to worry about. This phenomenon can also occur if the bladder is full due to the urge to urinate. Men should also pay attention to the hygiene of their lower body, clean their genitals more often, have sexual intercourse in moderation, pay more attention to their own health, and avoid inflammation such as prostatitis.

This phenomenon is morning erection, which is a normal physiological reaction of men. It is uncontrolled. Generally, if the bladder of men is full of urine before waking up in the morning, they often have morning erection. With the increase of age, the frequency and duration of penis erection will gradually decrease, which generally has no effect on the body.

Normal men will have morning erections or nocturnal erections. Morning erections refer to the erection of the penis when a man wakes up in the morning, while nocturnal erections refer to the automatic erection of the penis when a man falls asleep at night. If a man does not have morning erections or nocturnal erections, there may be something wrong with his reproductive system.

(1) Our internal organs are controlled by the sympathetic and parasympathetic nerves, and our sexual organs are no exception. Penile erection is controlled by the parasympathetic nerves of the sacral cord. When the parasympathetic nerves are excited, the penis will erect.

(2) Both the sympathetic and parasympathetic nerves have a certain degree of tension (i.e., a weak but persistent excitement), and they oppose each other like seesaws. When the sympathetic nerves are excited, the parasympathetic nerves are relatively inhibited.

(3) During the day, the sympathetic nervous system is relatively dominant in response to various stimuli from the environment. At night, when people are quiet and sleeping, especially during parasympathetic sleep, the parasympathetic nervous system is dominant, resulting in male penis erection and female vulva congestion.

There are two sayings in the folk saying: "Men pick up their pens at midnight, and women's lotus flowers bloom at midnight." This shows that our ancestors had already observed this physiological phenomenon.

All mature and normal males experience morning erections, but few know about nocturnal erections. Nocturnal erections refer to the erection of the penis when a person is asleep. Nocturnal and morning erections of the penis are one of the important indicators of male sexual function. Studies have found that men have spontaneous penile erections after a deep sleep. The number of erections varies greatly depending on age, physical condition, and sexual function. Generally speaking, young men have 7-8 erections per night.
